Exochorda racemosa ‘Niagara’ (PBR) is a deciduous flowering shrub noted for its strong spring display and tidy growth. In mid-spring, rounded buds open along the branches to reveal clear white flowers that brighten the plant before the foliage fully develops. The blossoms are carried along slightly arching stems, giving the shrub a light, flowing appearance while still maintaining a compact overall shape. Once flowering has finished, fresh green leaves form a neat canopy that remains through the growing season. Hardy and dependable in UK gardens, it grows best in fertile soil with good drainage and performs well in sunny or lightly shaded positions.
